theconnactic Posted April 15, 2013 Share Posted April 15, 2013 Did you try unplugging/replugging the monitor? All the best! P.S.: After the boot, after getting to that screen, i mean: boot as you did, when you get the distorted desktop, unplug and replug the VGA cable.

Rampage Dev Posted April 15, 2013 Share Posted April 15, 2013 Apple does not use VGA for Intel HD3000/4000 thus it does not work OOB. There have been reports of a kext edit that allows it to work with mixed results. 1 Link to comment https://www.insanelymac.com/forum/topic/287912-appleintelframebuffercapri-hd4000-vga-out-problem/#findComment-1907391 Share on other sites More sharing options...

True, specially on notebooks the results are mostly bad, there have been some more positive results on desktops. 1 Link to comment https://www.insanelymac.com/forum/topic/287912-appleintelframebuffercapri-hd4000-vga-out-problem/#findComment-1907414 Share on other sites More sharing options...
